I'm currently designing and implementing Big-Data processing pipelines for telemetry collection and billing. This involves working daily with Python, Pandas, Cassandra, Spark, Flask, PostgreSQL and the likes.

My pipelines are managing real-time consolidation and reconciliation of telemetry events, and supports: the definition of pricing matrix for resource variants, payment workflows, early fraud-detection, per-territory taxes, product and service taxonomy, discounts and coupons, generation of invoice PDFs, as well as all the European VAT idiosyncrasies.
